I have a '76 z that i had for a while, i just got the turn signals to work .

when i turn on my hazards only the right side flashes and the left doesnt.

Both signals work when i hit the switch but when i turn on my hazards only one side coems on.

If any one knows when the problem could be it would really be helpful.

I have to pass some inspection for the DMV b4 i can register the car.

Its most probably in the hazard switch itself. Unplug it and take it out, if you pull it to pieces (carefully) from memory you'll see 6? (maybe 8) contacts inside.

Clean off any corrosion and spray the contacts with WD40 or similar. Hmm then make sure that the wiring harness plug is making proper contact when you plug it in.

Good luck
